WHO GMP Certified Retatrutide API Supplier in Navi Mumbai, India | Aarise Pharmaceuticals

Aarise Pharmaceuticals is a WHO GMP certified Retatrutide API supplier serving pharmaceutical manufacturers, formulation companies, and research organisations in Navi Mumbai and across India. Retatrutide is a next-generation triple receptor agonist (GIP, GLP-1, and glucagon) representing one of the most promising new molecular entities in the global obesity and metabolic disease market. We supply Retatrutide API at 98%+ HPLC purity with complete batch documentation — making us one of India’s reliable Retatrutide API suppliers for both domestic manufacturing and international export.

What is Retatrutide?

Retatrutide (LY3437943) is an investigational triple agonist peptide that simultaneously targets GIP (glucose-dependent insulinotropic polypeptide), GLP-1 (glucagon-like peptide-1), and glucagon receptors. Developed by Eli Lilly, it represents the next generation beyond dual agonists like Tirzepatide. In Phase 2 clinical trials, Retatrutide demonstrated up to 24.2% weight loss at 48 weeks — one of the highest figures ever recorded in a clinical obesity trial.

Key characteristics of Retatrutide API:

• Mechanism: Triple GIP/GLP-1/Glucagon receptor agonism — superior weight loss vs. single or dual agonists
• CAS Number: 2381967-72-0
• Molecular Weight: Approximately 4,764 Da (peptide with fatty acid side chain)
• Dosage form: Subcutaneous injectable (weekly dosing)
• Therapeutic targets: Obesity, type 2 diabetes, NASH/NAFLD, cardiovascular metabolic syndrome
• Clinical status: Phase 3 trials ongoing as of 2025

Applications of Retatrutide API for Navi Mumbai Manufacturers

Subcutaneous Injectable Formulations

The primary dosage form for Retatrutide is a weekly subcutaneous injection. Navi Mumbai formulation companies can use our Retatrutide API for development of prefilled syringe or auto-injector formulations targeting obesity and type 2 diabetes. We provide the API in lyophilised form suitable for reconstitution, or as a solution intermediate for liquid-fill formulations.

Research and Development

Biotech and CRO companies in Navi Mumbai can source small quantities of Retatrutide API (1mg–100mg) for in vitro receptor binding assays, pharmacokinetic studies, and formulation development work. Our research-grade Retatrutide API (98%+ HPLC) is suitable for preclinical and early clinical research purposes.

Early Clinical Manufacturing

For Phase 1 or Phase 2 clinical trial supply, we can supply Retatrutide API with enhanced documentation packages including full characterisation data, process validation information, stability data, and regulatory filing support for IND (Investigational New Drug) applications.

Packaging for Navi Mumbai Delivery

• Research Quantities: 1mg, 5mg, 10mg, 50mg, 100mg in sealed glass vials (lyophilised)
